Weather Exploratory Data Analysis

Background
The file ‘WeatherDownloads_202005_v002.Rmd’ contains code for dowloading and processing historical weather data as contained in METAR archives hosted by Iowa State University.
Data have been dowloaded and processed for several stations (airports) and years, with .rds files saved in “./RInputFiles/ProcessedMETAR”.
This module will perform exploratory data analysis on the processed weather files.
Data Availability
Each processed data file contains one year of hourly weather data for one station. Files are saved as ‘./RInputFiles/ProcessedMETAR/metar_kxxx_yyyy.rds’ where xxx is the three-digit airport code and yyyy is the four-digit year.
Each file contains the following variables:
- METAR (chr) - the extracted portion of the METAR based on a regex string
- WindDir (chr) - the previaling wind direction in degrees, stored as a character since ‘VRB’ means variable
- WindSpeed (int) - the prevailing wind speed in knots
- WindGust (dbl) - the wind gust speed in knots (NA if there is no recorded wind gust at that hour)
- Dummy (chr) - artifact, always a blank space
- Visibility (dbl) - surface visibility in statute miles
- TempC (int) - temperature in degrees Celsius
- DewC (int) - dew point in degrees Celsius
- Altimeter (int) - altimeter in inches of mercury
- SLP (int) - the raw sea-level-pressure reading from the METAR
- FahrC (chr) - the raw temperature string pulled from the METAR (Tttttdddd) where tttt is the Fahrenheit temperature recorded in Celsius and dddd is the Fahrenheit dew point recorded in Celsius
- dtime (dttm) - the date-time associated with the observation
- origMETAR (chr) - the full METAR associated with the observation
- TempF (dbl) - the Fahrenheit temperature associated with converting FahrC to Fahrenheit
- DewF (dbl) - the Fahrenheit dew point associated with converting FahrC to Fahrenheit
- modSLP (dbl) - Sea-Level Pressure (SLP), adjusted to reflect that SLP is recorded as 0-1000 but reflects data that are 950-1050
- nSKC (int) - number of times ‘SKC’ (human-confirmed cloud-free) is recorded in the observation (should be 0 or 1)
- nCLR (int) - number of times ‘CLR’ (austomated-sensor cloud-free) is recorded in the observation (should be 0 or 1, and should never have both nSKC>0 and nCLR>0)
- cloudn (chr) - the nth cloud layer recorded in the METAR (layers begin with FEW, SCT, BKN, OVC or VV)
- cTypen (chr) - the cloud type of the nth cloud layer (FEW, BKN, SCT, OVC, or VV)
- cLeveln (dbl) - the cloud height in feet of the nth cloud layer
- wType (fct) - highest level of obscuration recorded in the METAR (VV > OVC > BKN > SCT > FEW > CLR/SKC)
- year (dbl) - year of the observation
- monthint (dbl) - month of the observation as a number (e.g., 6=June)
- month (fct) - month of the observation as three-character abbreviation, saved as a factor (e.g., Jun=June)
- day (int) - day of the month of the observation
Base Functions Available
There are several functions available for analysis:
plotCountsByMetric() - bar plots for counts by variable
plotNumCor() - plot two numeric variables against each other
plotFactorNumeric() - boxplot a numeric variable against a factor variable
corMETAR() - correlations between METAR variables
lmMETAR() - linear regression modeling for METAR variables
basicWindPlots() - plot wind speed and direction
getWindDirGroup() - convert wind direction to a grouping (e.g., N for 320-360-40)
consolidatePlotWind() - show frequency plots of wind direction, city, and month

The getWindDirGroup() function maps wind direction to a category such as NNE. Because the METAR data are recorded in units of 10 degrees, either 4 groupings (90 degrees each) or 12 groupings (30 degrees each) are preferred, so that each category has the same underlying number of buckets:

Directing Output to a Separate File
There is a lot of good information in the EDA, but it can be overwhelming to have everything in one place. Perhaps a wrapper function can be built allowing for outputs to be piped to a given file:
wrapCombinedEDA <- function(readFile,
readPath="./RInputFiles/ProcessedMETAR/",
mapFileNames=cityNameMapper,
desc=NULL,
writeLogFile=NULL,
writeLogPDF=NULL,
writeLogPath=NULL,
appendWriteFile=FALSE,
...
) {
# Read in the requested file
tbl <- readRDS(paste0(readPath, readFile))
# Find the description if it has not been passed
if (is.null(desc)) {
desc <- getLocaleDescription(readFile, mapper=mapFileNames)
}
# Helper function that only runs the combinedEDA() routine
coreFunc <- function() { combinedEDA(tbl=tbl, desc=desc, mapFileNames=mapFileNames, ...) }
# If writeLogPDF is not NULL, direct the graphs to a suitable PDF
if (!is.null(writeLogPDF)) {
# Prepend the provided log path if it has not been made available
if (!is.null(writeLogPath)) {
writeLogPDF <- paste0(writeLogPath, writeLogPDF)
}
# Provide the location of the EDA pdf file
cat("\nEDA PDF file is available at:", writeLogPDF, "\n")
# Redirect the writing to writeLogPDF
pdf(writeLogPDF)
}
# Run EDA on the tbl using capture.output to redirect to a log file if specified
if (!is.null(writeLogFile)) {
# Prepend the provided log path if it has not been made available
if (!is.null(writeLogPath)) {
writeLogFile <- paste0(writeLogPath, writeLogFile)
}
# Provide the location of the EDA log file
cat("\nEDA log file is available at:", writeLogFile, "\n")
# Run EDA such that the output goes to the log file
capture.output(coreFunc(),
file=writeLogFile,
append=appendWriteFile
)
} else {
# Run EDA such that output stays in stdout
coreFunc()
}
# If writeLogPDF is not NULL, redirect to stdout
if (!is.null(writeLogPDF)) {
dev.off()
}
# Return the tbl
tbl
}filePath <- "./RInputFiles/ProcessedMETAR/"
